IHB4EB182K Equivalent & Substitute Parts

Part Overview

The IHB4EB182K is a 1.8 mH unshielded wirewound inductor manufactured by Vishay Dale, rated for 2.5 A continuous current with a maximum DC resistance of 360 mOhm. This radial, vertical cylinder through-hole component is designed for general-purpose inductive filtering and energy storage applications in electronic circuits.

Substitute parts become necessary when the original manufacturer's stock is unavailable, when supply chain constraints require alternative sourcing, or when design flexibility permits the use of functionally equivalent components from different manufacturers. The availability of qualified alternatives ensures design continuity and project timeline adherence.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IHB4EB182K is determined by the following critical parameters:

• Inductance Value: Must be 1.8 mH (±10% tolerance acceptable per industry standard)
• Current Rating: Substitute must support minimum 2.5 A; higher ratings are acceptable
• DC Resistance: Maximum 360 mOhm; lower values are acceptable
• Shielding Configuration: Unshielded specification must be maintained
• Mounting Technology: Through-hole radial package required
• Core Material & Construction: Wirewound construction acceptable; drum core or ferrite core alternatives acceptable if electrical parameters are met

The 1140-182K-RC from Bourns Inc. qualifies as a direct substitute based on these criteria. It maintains the same inductance value, exceeds the current rating requirement (2.8 A vs. 2.5 A), matches the DC resistance specification, preserves the unshielded configuration, and uses compatible through-hole radial packaging with wirewound drum core construction.

Parameter Comparison

Engineering Selection Recommendations

The 1140-182K-RC is a qualified substitute for the IHB4EB182K based on electrical and mechanical parameter alignment. The substitute component meets or exceeds all specified performance criteria: identical inductance and DC resistance values, higher current rating capacity (2.8 A vs. 2.5 A), and matching through-hole radial packaging.

The Bourns 1140-182K-RC carries ROHS3 compliance certification and REACH unaffected status, providing regulatory compliance documentation. The component is classified as Active product status, ensuring continued manufacturer support and availability.

Physical dimensions differ slightly: the substitute measures 1.500" diameter (38.10 mm) with 1.030" seated height (26.16 mm). PCB layout verification is required to confirm dimensional compatibility within the target application's spatial constraints.

Frequently Asked Questions (FAQ)

Q: Can the 1140-182K-RC be used as a direct replacement for the IHB4EB182K in existing designs?

A: Yes, provided PCB footprint and spatial clearance accommodate the substitute's physical dimensions (1.500" Dia × 1.030" height). Electrical performance is equivalent or superior across all specified parameters.

Q: What is the significance of the higher current rating in the substitute part?

A: The 1140-182K-RC's 2.8 A rating exceeds the IHB4EB182K's 2.5 A requirement, providing additional thermal margin and component longevity in the application. This represents an improvement, not a limitation.

Q: Are there any compliance or regulatory differences between these parts?

A: The 1140-182K-RC provides explicit ROHS3 compliance and REACH unaffected certification. If regulatory documentation is required for your application, the Bourns substitute offers certified compliance status.

Q: How do the core constructions differ between these inductors?

A: The IHB4EB182K uses wirewound construction; the 1140-182K-RC uses drum core wirewound construction. Both are unshielded and deliver identical inductance and DC resistance specifications. The drum core design may offer improved thermal characteristics.

Q: What should be verified before implementing this substitution?

A: Confirm PCB layout accommodates the substitute's radial package dimensions. Verify circuit operating current remains within 2.8 A rating. Validate that unshielded configuration meets EMI/RFI requirements of the target application.
